The investigation opened by the Manhattan U.S. attorney’s office is examining whether some of the committee’s donors gave money in exchange for policy concessions, influencing administration positions or access to the incoming administration, the Journal said.

The probe could present another legal threat for Trump and his White House, which already faces a web of lawsuits and probes into subjects such as the Trump campaign’s contacts with Russia, hush-money payments to women made by the president’s former lawyer and spending by Trump’s foundation.

The investigation into the inaugural committee partly stemmed from materials seized in a probe into the dealings of former Trump lawyer Michael Cohen, the Journal reported. Cohen was sentenced on Wednesday to three years in prison for crimes including orchestrating the hush payments in violation of campaign laws.
